Okay, you don’t have a board type un-commented, and you’re using GPIO0 for something.

Presumably the custom board configuration section of Settings.h looks like this…

#else

  #warning "Custom board configuration is used"

  #define BOARD_BUTTON_PIN            0                     // Pin where user button is attached
  #define BOARD_BUTTON_ACTIVE_LOW     true                  // true if button is "active-low"

  //#define BOARD_LED_PIN             4                     // Set LED pin - if you have a single-color LED attached
  //#define BOARD_LED_PIN_R           15                    // Set R,G,B pins - if your LED is PWM RGB
  //#define BOARD_LED_PIN_G           12
  //#define BOARD_LED_PIN_B           13
  //#define BOARD_LED_PIN_WS2812      4                     // Set if your LED is WS2812 RGB
  #define BOARD_LED_INVERSE           false                 // true if LED is common anode, false if common cathode
  #define BOARD_LED_BRIGHTNESS        64                    // 0..255 brightness control

#endif

So GPIO0 is being used by Edgent as your credentials reset pin. You should read this…
